Search

• run locally, search files
• run pattern against top 500 gems
• replace, with list of captures/location => text/capture/location

Debugging

• allow defining patterns as methods and allow calling them from other patterns

UI

• show last value attempted as a match (as popover?) (already part of the JSON response)
• improve display of Ruby AST. One day use astexplorer's?

Editing

• generate URLs to be able to restore state (not saved to DB, just long URL with all the data in it)
• button to produce pattern from ruby code (e.g. hello(42, _) => (send nil? :hello (int 42) _))
• same, but to add/remove to an existing pattern (seems hard to produce something good)

Code

• Create README / contributing / ...
• Spec for server (with VCR)
• Setup CI
• Add rubocop

A quick win to improve the rendering of the Ruby AST would be to use a Bootstrap code block, instead of a <div>. This would preserve the whitespace included by the output of to_s.

I would have opened a PR, but I can't get the server to run, and am not familiar with Parcel to debug it.

Hey @marcandre. While trying to run np locally, I found that:

1. It requires Ruby 3.1 (3.2 won’t work), but doesn’t have a .ruby-version file.
2. It has a gemspec, but is a service. Or can it be used as a gem too?
3. Running rake serve isn’t documented in Readme. Also, I think I need to compile assets first.
4. There is a build_assets rake task which seems to require Parcel (could it be added to package.json?). But even after installing it, I cannot figure out how to build the assets.
